  • Induction heating cookers comprise a top plate and induction heating means including an induction heating coil disposed below the top plate and an inverter supplying a high-frequency current to the induction heating coil.
  • Some induction heating cookers are provided with another type of heating means such as nichrome wire coils (radiant heater). Appearances of the induction heating cooker are reduced when the heating means are viewed through the top plate from outside.
  • JP-B-6-2389 discloses an induction heating cooker including a top plate made of a white ceramic glass or a transparent glass with an underside to which a heat-resistant paint is applied.
  • Induction heating cookers have recently been provided with a display in the top plate so that an output state of the heating means can readily be confirmed.
  • the display comprises a plurality of light-emitting diodes provided below the top plate and energized so that the output state of the heating means is displayed.
  • the top plate made from the white ceramic glass or the transparent glass with the underside coated with the heat-resistant paint as described above, the top plate cannot transmit light emitted by the light-emitting diodes of the display.
  • the top plate when the top plate is made of a transparent glass coated with paint, part of the applied paint corresponding to the display is removed so that the top plate transmits the light emitted by the light-emitting diode transmits the light.
  • the paint is partially removed from the top plate, components of the light-emitting diode are viewed through the paint-removed part of the top plate even when the light-emitting diode is turned off, whereupon the appearances of the induction heating cooker is reduced. Further, light emitted by the light-emitting diode leaks through the paint-removed part of the top plate or the interior of the cooker below the top plate can be viewed when illuminated by external light.
  • the display is disposed near the induction heating coil in order that heating by the induction heating coil may definitely be indicated. Accordingly, when paint is removed from the part of the top plate corresponding to the display, the induction heating coil is viewed through the paint-removed part, whereupon the appearances of the induction heating cooker are reduced.
  • the light-emitting diode comprises one emitting red light and the top plate is made of a colored glass.
  • the colored glass allows light with the wavelength longer than the red one to pass therethrough but cuts off visible light.
  • the interior of the cooker below the top plate is hard to view.

  • the induction heating coil is disposed near the top plate. Accordingly, the induction heating coil is sometimes viewed even when the top place comprises a colored glass which transmits light emitted by the light emitting element.
  • the light transmissible thin film coated on the top plate can reliably prevent the induction heating coil from being viewed above the top plate.
  • the top plate transmits at least part of the light emitted by the light emitting element while the thickness of the light transmissible thin film is adjusted and the material for the thin film is selected so that the top plates with a number of colors and color tones are constructed.

  • the induction heating assembly 19 is screwed in the casing 6 so as to be located below the induction heating sections 8 and 9 while the induction heating coils 3 and 4 are adjacent to the underside of the top plate 7.
  • a board mounting member 20 is screwed to a front half of the outer periphery of the induction heating assembly 19.
  • a printed board 21 is mounted on the board mounting member 20.
  • the aforesaid LED's 22 are mounted on the printed board 21.
  • the board mounting member 20, the printed board 21 and LED' s 22 constitute the coil output display sections 11 and 12.
  • a circular heat-insulating container or base 23 is fixed in the casing 6 and has an open top.

  • the heating units are turned on and off when the power switch 30 is turned on and the respective dials 31 to 34 are depressed. Further, output levels of the heating units are adjusted when the respective dials 31 to 34 are turned. For example, when the induction heating coil 3 is used for cooking, a pot is placed on the induction heating section 8 and the dial 31 is depressed. The induction heating coil 3 is then energized at maximum output, so that all the LED's 22 for the induction heating coil 3 are turned on.

  • the top plate 7 transmits light emitted by the LED's 22 turned on. Accordingly, the user counts the number of energized LED's 22 or views the numeral printed near the energized LED 22, thereby confirming the output state of the induction heating coil 3. Particularly in the embodiment, LED's 22 are disposed in the vicinity of the induction heating coil 3. Accordingly, although the induction heating coil 3 does not heat up itself, the user can find that the induction heating coil 3 is energized when viewing the energized LED's 22.
  • the top plate 7 is made by forming the light transmissible thin film 15 on the underside of the transparent glass. Accordingly, the top plate 7 can transmit light emitted by LED's 22 and 26 when the thickness of the light transmissible thin film 15 is adjusted. Thus, a part of the light transmissible thin film 15 need not be removed from the top plate 7 in order that the top plate 7 may transmit the light emitted by LED's 22 and 26. Further, the color tone of the transparent glass plate on which the thin film 15 is formed can be varied according to the thickness of and material for the thin film 15. Consequently, the color of the top plate 7 can be diversified.
  • the light transmissible thin film 15 formed on the underside of the top plate 7 has a function as a mirror. More specifically, when the characters 14a and the like of the caution display section 14 and the light transmissible thin film 15 are spaced away from each other, the characters 14a printed on the top plate 7 are disadvantageously viewed as being'doubled. In the foregoing embodiment, however, the characters 14a and the like of the caution display section 14 are printed on the underside of the top plate 7 and the light transmissible thin film 15 are then formed on the printed characters 14a and the like. As a result, the characters 14a and the like of the caution display section 14 and the light transmissible thin film 15 are close to each other. Accordingly, even when reflected in the light transmissible thin film 15 as the mirror, the characters 14a and the like can be prevented from being hard to view since the reflected characters substantially correspond with directly viewed characters.
  • Infrared rays emitted by the radiant heater 5 would be reflected in the light transmissible thin film 15 such that heat is shut up in the base 23.
  • a painted film 16 is applied to a region of the heater heating section 10 on the underside of the top plate 7 without the light transmissible thin film 15 being formed thereon. This prevents an excessive increase in the temperature of the radiant heater 5 and a sudden drop in the heating efficiency.
  • the radiant heater 5 can be prevented from being viewed externally.
  • the circumferential edge of the paint film 16 overlaps the thin film 15. Accordingly, the underside of the top plate 7 does not include any portion on which neither paint film 16 nor light transmissible thin film 15 is formed.
  • FIG. 6 illustrates a second embodiment of the invention. Only the differences of the second embodiment from the previous embodiment will be described. Identical or similar parts are labeled in the second embodiment by the same reference symbols as in the first embodiment.
  • a number of heat-radiating portions 41 are provided on a part of the light transmissible thin film 15 corresponding to the heater heating section 10. Each heat-radiating portion 41 is formed into the shape of a circular hole.
  • the heat-radiating portions 41 are formed with no light transmissible thin film, namely, the light transmissible thin film on the underside of the top plate corresponding to the heater heating section 10 is polka-dotted.
  • heat generated by the radiant heater 5 can also be prevented from being shut up in the base 23 when a part of the light transmissible thin film 15 is removed from the underside of the heater heating section 10 of the top plate 7.
  • a part of the radiant heater 5 is visible through the heat-radiating portions 41. However, when each one of the heat-radiating portions 41 is rendered small, degradation of appearance can be limited even though the radiant heater 5 is visible through the heat-radiating portions 41.

  • Each LED 53 serves as light-emitting element and emits green light having a wavelength differing from that of each LED 22 and ranging from 500 to 550 nm. Accordingly, the top plate 7 transmits almost no light emitted by each LED 53.
  • portions of the top plate 7 corresponding to the respective LED' s 53 serves as transmission openings on which the light transmissible thin films 15 are not formed.
  • Automatic cooking can be carried out using the induction heating coils 3 and 4 in the embodiment.

Further, the thickness of the light transmissible thin film or the translucent film may be set at several tens to several hundreds microns according to the wavelength range of the light emitting element emitting light which is to be transmitted therethrough.
